Analysis of Asymmetric Heating on a Scaled High Temperature Gas Reactor Experiment During a Pressurized Conduction Cooldown

Creator:: Moore, Thomas
Abstract:: Among the candidates for the next generation of nuclear power plant is the high temperature gas reactor (HTGR). Since the HTGR does not have the same operational history as water cooled reactors do in the United States, investigation into the response of different accident phenomena is still an active area...
Resource Type:: Dissertation

On the mechanism transition of power transient critical heat flux

Creator:: Yan, Yikuan
Abstract:: The reactivity-initiated accident (RIA) accident has stirred wide interest for the need of designing advanced and high tolerance fuels for next generation nuclear power plants. For pressurized water reactors (PWRs), the accidentally induced reactivity pulse adds transient energy input to the fuel. As a result, boiling may happen locally. Boiling...

Special Nuclear Material Classification and Mass Content Estimation Using Temporal Gamma-Ray Spectroscopy and Machine Learning Methods

Creator:: Curtis, Jessica R.
Abstract:: Improving the methods used for the detection and estimation of fissile material mass content is essential to nuclear security and safeguards to ensure special nuclear material (SNM) accountability, control, safety and security. With the continued expansion of the nuclear industry and the need for safe management of spent fuel, improving...

Caution! High Water: A Historical Archaeological Investigation of the Champoeg Townsite (ORMA26) after the 1861 Flood

Creator:: Hill, Cayla L.
Abstract:: The Champoeg townsite first developed due to its ideal settlement and trade location within the Willamette Valley, becoming the ‘legal birthplace of Oregon’ in 1843. However, by 1860 Champoeg’s significance had begun to decline, and in December of 1861 a devastating flood wiped out the townsite. Archaeological excavations took place...

At River’s Edge: An Examination of Overseas Chinese Settlements in Northern Oregon during the Exclusion Act Era

Creator:: Maddoux, Maryanne F.
Abstract:: The written history of Oregon spanning the late 18th and early 19th centuries lacks evidence of the contributions made by the Overseas Chinese communities who existed in Oregon during this period. The purpose of this examination is to study the Overseas Chinese communities which resided in the cities of The...

Material Expressions of Class, Status and Authority amongst Commissioned Officers at Fort Yamhill and Fort Hoskins, Oregon, 1856-1866

Creator:: Eichelberger, Justin E.
Abstract:: During the 19th century the United States Army was a military institution characterized by a hierarchical system of authoritative, social and economic inequality between members of its different military grades. Although necessary for insuring military discipline within the Army this system of inequality also influenced the non-military social lives of...

Organic Phase Inter-Ligand and Metal-Ligand Speciation in TALSPEAK and ALSEP Solvent Extraction Systems

Creator:: Gullekson, Brian J.
Abstract:: Partitioning of trivalent actinides (in particular, americium and curium) from the fission produced light lanthanides is a major concern of used nuclear fuel reprocessing for the purposes of waste disposal. Several solvent extraction processes have been developed to address these chemically difficult separations. The historically employed TALSPEAK Process utilizes di-2-ethylhexyl...

Study on Depressurized Loss of Coolant Accident and its Mitigation Method Framework at Very High Temperature Gas Cooled Reactor

Creator:: Gutowska, Izabela
Abstract:: To understand how a Depressurized Loss of Forced Convection (D-LOFC) initiated from a double-ended guillotine break may affect further operation of a High Temperature Gas Cooled Rector (HTGR), thorough understanding of each specific stage of this event is required. Key considerations that need to be determined is the amount of...

Modification of Lower Plenum Structure for Mixing Promotion during Normal Operation of the High Temperature Gas Cooled Reactor

Creator:: Gradecka, Malwina
Abstract:: Since High Temperature Gas-cooled Reactors are being considered as most promising design of upcoming IV Gen reactors, thus key research areas were identified to address safety aspects of this design. Number of simulations and experiments need to be conducted in this field. In this study thermal-hydraulics aspects of coolant flow...

Development of a binary mixture gas composition instrument for use in a confined high temperature environment

Creator:: Cadell, Seth R.
Abstract:: With recent advancements in material science, industrial operations are being conducted at higher and higher temperatures. This is apparent in the nuclear industry where a division of the field is working to develop the High Temperature Gas Reactor and the Very High Temperature Gas Reactor concurrently. Both of these facilities...
